phenotypic plasticity


Also found in: Encyclopedia, Wikipedia.

phenotypic plasticity

or

environmental variation

the ability of an organism to alter greatly its PHENOTYPE depending upon environmental conditions. The phenomenon is seen most clearly in plants, perhaps because they are fixed in the ground. For example, a dandelion will produce an erect habit with long flower stalks if in a garden border with other plants. Another dandelion with a similar genotype will produce a PROCUMBENT habit with short flower stalks if grown in a garden lawn.

This project will uncover the spatiotemporal dynamics of hfscs fate decisions and establish the role of the niche in this process (aim1), Decipher key gene-regulatory networks and epigenetic barriers that control phenotypic plasticity (aim2), And discover druggable signaling networks that drive bi-directional reprogramming of hfscs and their progeny (aim3).
Phenotypic plasticity theory suggests that defenses should be costly to produce; otherwise organisms would always produce them, and they would not be plastic.

Adaptive phenotypic plasticity (the ability of a single genotype to change its phenotype in res ponse to environment cues) is often key to optimizing crypsis in animals whose habitat is heterogeneous through space or time (Umbers et al.
I therefore suggest that these plants showed phenotypic plasticity across microclimates at a location.
In other taxa, changes in sexual size dimorphism may result from sexual differences in phenotypic plasticity (Stillwell & Davidowitz, 2010; Marquez & Saldamando-Benjumea, 2013).

Phenotypic plasticity, defined as the capacity of expressing alternative patterns of morphology, physiology and/or behavior in response to environmental pressures, is the source of morphological variability within natural populations (Schlichting, 1986).
Results showed that bleak populations are able to display wide phenotypic plasticity in small Mediterranean-type rivers.
Phenotypic plasticity in response to environmental heterogeneity is an important adaptive component of plant strategies.
In the context of a rapid climate change, phenotypic plasticity can be a crucial determinant of plant response, both in short-and long term (Nicotra & al.
1998), phenotypic plasticity is often adaptive, providing organisms greater chances of survival and reproduction under heterogeneous environments (Via et al, 1995).
